Can this be used to detect a tub that has overflowed?

Yes. I believe so. As long as you place it out side the tub wall on the floor where potential water will overflow, it will work. The leak detector 4 sensors at the bottom of the device to alarm you whenever there is a pool of water. Note : There is also a sensor on the top ( two parallel lines) which can detect a drip from the faucet also. Hope that helps.

Can the audible alarm be silenced from the iphone app?

How do we silence the alarm in case we are cleaning water from the spot. Is it single click, double click or something else on the sensor button?
